Filed: 1933-10-06
Abstract: 428,365. Steam turbine plant. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Oct. 6, 1933, No. 27584. Convention date, Oct. 6, 1932. [Class 110 (iii)] In a turbine plant for ship propulsion comprising high and low pressure turbines working in series, the H.P. turbine 2 drives the propeller 4 through an electric coupling comprising a generator 10 and a motor 5, and the L.P. turbine 3 drives direct through a disconnectable coupling 6 or through a similar electric coupling. The turbines are controlled so that at cruising speed the output of the L.P. turbine is only a fraction of that of the H.P. turbine, while with increasing power demand a greater proportion of the output is transferred progressively to the L.P. turbine, so that at full speed, when the power demand is very large, the output of the H.P. machine is only a small fraction of that of the L.P. machine. To secure this result, a throttle valve 13 or nozzle regulator is arranged between the turbines in order to increase the back pressure of the H.P. turbine 2. The H.P. turbine may be driven by steam with an inlet pressure varying within wide limits, the boiler 1 having a variable characteristic. The H.P. turbine may exhaust to a number of L.P. turbines arranged on different propeller shafts, and it may drive a number of separate generators coupled independently to motors on the different shafts. Control valves 13, 14 are provided, and the L.P. turbine may be byepassed. The speed of the propeller is varied by a pole changing switch 12, and a device 11 is arranged to alter the polarity on reversing.

Title: Improvements in and relating to spinning mules and twiners
IPC: D01H3/12
Filed: 1938-09-22
Abstract: 519,540. Spinning mules. LEES & CO., Ltd., A., and GUY, W. Sept. 22, 1938, No. 27599. [Class 120 (ii)] A spinning mule or twiner having the usual weighting arrangements is provided with a brake which is automatically applied only by the downward movement of the counterfaller; thus absorbing energy normally applied to lift the weights and thereby reducing the lift imparted thereto and correspondingly reducing their fall when the counterfaller rises and the yarn slackens. As shown an arm 13 fixed to the counterfaller shaft 14 is connected by a chain or the like to an arm 11 loosely mounted on a spindle 6 carrying a brake drum 8 which has a ratchet wheel 16 secured thereto and engaged by a pawl 15 on the arm 11; the drum 8 is engaged by a weighted band 9 secured at one end to a rod 7 carried by the brackets 5 which also carry the spindle 6. When the counterfaller 17 is pulled down, the arms 13, 11 are lifted and the ratchet wheel and drum are turned against the braking action of the weighted belt 9 thus braking the counterfaller and reducing the lift of the weights. When, on the other hand, the yarn slackens during the inward run and the counterfaller rises there is a corresponding reduction in the fall of the weights and less likelihood of injury to the yarn.

Abstract: 1,197,348. Once-through steam generator WAAGNER-BIRO A.G. 11 June, 1968 [16 June, 1967], No. 27807/68. Heading F4A. A heat exchanger comprises at least two banks of tubes within a pressure vessel, medium to be heated being conveyed in at least one bank in co-current flow with respect to the flow of heating medium and conveyed in another bank in counter-current flow, and one or more of a number of pipes entering the pressure vessel for connecting the banks of tubes to the outside of the pressure vessel are disposed axially and centrally within the pressure vessel and heatshielded from the heating medium by one or more centrally disposed tubular heat shields. In the once-through steam generator shown in Fig. 2, a feed water inlet pipe 28 and header 31 are followed by a bank 6 of helical, spiral or involute evaporator tubes in which the steam may be slightly superheated. The bank 6 is connected by bends 7, supporting tubes 8 and bends 9 to an upper bank 10 of, e.g. helical, superheater tubes connected by return bends 11 to discharge headers 32 from which the steam passes via pipes 27 to, e.g. a steam turbine. The steam returns to the generator via inlet pipes 30 and headers 34 and flows through another set of tubes in the upper bank 10 to discharge headers 33 and pipes 29. The two sets of tubes of the bank 10 alternate in the radial or axial direction, or in both directions. If these tubes are helical, the two sets are disposed in coaxial cylinders, the tubes in each cylinder being wound in the same direction and the direction of winding being reversed in radially adjacent cylinders. The headers 31- 34 are insulated, and the pipes 27, 28, 29 are shielded from the heating medium by a tubular heat shield 12. Heating medium from a nuclear reactor enters the pressure vessel 14 at 1 and leaves at 2, so that it flows co-currently with respect to the tube bank 10 and countercurrently with respect to the tube bank 6. The tubes of the bank 10 are secured to the supporting tubes 8 by means of sleeves 24 or rings. Support rods 22, 25 are secured to star-shaped members 23, 26. The tube banks 6, 10 and their supporting structure are secured to the cover 21 of the pressure vessel 14 so that they can be removed with the cover. In a modification, the headers are located outside the pressure vessel 14, and two concentric heat shields are provided for the pipes.

Title: Improvements in data handling systems
IPC: H04L12/54
Filed: 1963-07-16
Abstract: 969,314. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 16,1963 [July 17, 1962], No. 28028/63; Heading G4C. ;  A storage device sequentially scans a number of data sources, stores the variable length data  messages received in corresponding parts of the store and generates control words which allow the messages to be fed to a utilisation device e.g.a  computer in the order in which their last bits are received in the store. As described the sources. are scanned and when it is, detected that a source has just become active a portion of the store is selected and its address is written in a control word associated with the source. The control words, one for. each source, are held in a separate control word store. During successive scans further, bits of the message are received and compiled in the portion of the store until the end of the message, which may be in start-stop or startcheck code, is received. The first available control word of a second set of control words is then selected and the address of the message is recorded in this control word.When the central computer requires information the control words of  the second set are taken in order and thus the messages are read into the computer in the order in which their reception in the store is completed. The control word store is scanned by a counter 118 which steps through the first thirty positions at a relatively low speed, each of these corresponding to a source being scanned, and at each stage the corresponding control word is temporarily fed out-to a register 116 from where a portion allocated for the address of a message may be passed to register 215 for setting the address or for resetting it at the start or end of the message. The next step 31 of the counter: corresponds to receiving data from the central computer and steps 32- 63 correspond to selecting the second set of control words The scanning over steps 32-63 is at a higher rate than: over steps: 1-3.0,extra stepping pulses being generated by an oscillator 201. A pair of counters 209, 213 record the number of messages which have already passed to the central computer, and the number of complete messages which have been stored. When passing messages to the central computer the oscillator 201 passes  the additional pulses to the scanner 118 and simultaneously steps counter 210 until a comparator 208 detects that this is the same as the count in the counter 209, at which time a gate 202 is closed. The scanner 118 is then set to the correct controlword. A comparator 212 similarly operates for allotting the control words to messages when they have been received completely.

Title: A method for making a predetermined metallic pattern on an insulating base
IPC: H05K3/20
Filed: 1953-10-12
Abstract: 724,380. Ornamenting. GENERAL ELECTRIC CO. Oct. 12, 1953 [Oct. 10, 1952], No. 28044/53. Drawings to Specification. Class 93. [Also in Group XXXVI] A metallic pattern is produced on a base of insulating material by sticking a thin flexible metal sheet to a thin, flexible non-elastic sheet having both surfaces protected from attack by an etching solution, protecting selected areas of the exposed surface of the metal sheet against attack by the etching solution, etching away the unprotected areas, pressing the etched surface against an insulating base to join the remaining metal areas firmly thereto, and stripping off the non-elastic sheet. The non- elastic sheet may comprise an aluminium foil coated on both sides with polyethylene, and the metal sheet may be of aluminium, coated with copper on the side which is bonded to the first sheet. The exposed aluminium surface is coated with a light-sensitive emulsion over which a photographic negative of the pattern is placed. After exposure to light, the unexposed. portions of the emulsion are removed by a developing solution and the assembly etched to remove the thus-exposed metal. Several thin sheets of uncured phenolic resin are placed in a laminating press and the top sheet coated with a thermo-setting adhesive against which the etched face of the assembly is placed. Heat and pressure are applied to bond the sheets into a rigid board into the surface of which the etched pattern is forced. The non-elastic sheet is then removed and any polyethylene remaining on the surface of the completed board is removed by means of a solvent such as benzine. A second pattern may be similarly formed on the other surface of the board.

Abstract: 647,165. Lathes. MATTHEY, A. MURBACH-. Oct. 21, 1947, No. 28105. Convention date, June 14, 1946. [Class 83 (iii)] An automatic lathe of the type described in Specification 647,164, in which a tool-holder 2 carrying automatically-adjustable tools revolves round the axis of bar stock 101 fed through a guide by means of two feed-wheels, the driving-wheel 103 for the bar feed is connected to a cam-operated feed lever 113 and to a cam-operated locking member 116, the latter locking the driving-wheel during the return movement of the feed-lever. The driving feed-wheel 103 and a friction-wheel 104 are mounted on a shaft 103a which is journalled in one end of a lever 107. An adjustable spring 109 pivots the lever about a universal joint comprising a cross-shaped member 130 with its arms engaged in heartshaped lugs 132 on the lever and in lugs 131 on the machine frame and so presses the wheels 104 and 103 into engagement with, respectively, a driving cylinder 105 and a second grooved feed-wheel 102, both of which are mounted on a shaft 102a; the second feed-wheel may be replaced by a spring-pressed roller. A shaft 113a is rotatably and slidably mounted within the shaft 102a and carries, at one end, the lever 113 engaging a feed-cam 126 and, at the other end, a cone 114 engageable with an internal taper on the cylinder 105. A locking cone 116 engageable with another taper on the cylinder is mounted on a shaft 119 slidable within the shaft 113a and is prevented from rotating by a fork 117 and pin 118. A lever 121 pivoted at 122 bears on the shaft 119 and on a cam 123 on the cam-shaft 127. In operation, the rise on the cam 126 acts on the lever 113 to rotate the cylinder 105 through the engaged cone 114 and, while the lever is in contact with the dwell at the top of the cam, the cam 123 acts on the lever 121 to move the shaft 119 axially inwards. Through the spring 120, the locking cone is engaged with the cylinder 105 and then the middle part 124 of the shaft 119 disengages the driving cone 114. When the fall on the cam 126 has allowed the lever 113 to return to its starting position, the cam 123 allows the shaft 119 to move out under the action of spring 120, spring 125 disengages the locking cone and spring 115 re-engages the driving cone.

Title: Arrangement for signalling over a two wire line
IPC: G08C19/02
Filed: 1949-11-03
Abstract: 662,222. Electric control systems. TELEFONAKTIEBOLAGET, L. M. ERICSSON. Nov. 3, 1949. [Nov. 5, 1948] No. 28196/49. Class 40 (i). [Also in Group XXXIX] In a system in which different signals are transmitted by the insertion of different resistances in a two-wire line loop the signalling circuit includes at the receiver an adjustable impedance (e.g. a thermistor) which automatically regulates the current in the line to a fixed value and the receiving device detects the magnitude of the change in the voltage across the line loop resulting from the insertion of a resistance in the loop. In the embodiment of Fig. 4 the invention is applied to setting a register RM in accordance with signals transmitted from a telephone subscriber's substation T. The impedance X automatically changes its resistance to maintain the current in the line substantially constant during signalling. Each of the keys K1 .. Kn inserts a resistance r1 ... rn in the loop and to each key there corresponds a pair of tubes such as V11, V12. These pairs differ only by the grid bias batteries E1 ... En having different voltages. Normally V11 is biassed negatively by the voltage drop in r1 and V12 is biassed positively. Relays R1 ... Rn are therefore normally operated as is relay AR also. When a key is depressed the impedance X maintains the current constant and the voltage across condenser C and resistance M and therefore the grid potential of tubes V11 ... Vn1 increases in proportion to the value of the resistance inserted in the loop. The resulting increase in anode current in these tubes decreases the bias of tubes V12 ... Vn2 and some or all of the relays R1 ... Rn relapse. The arrangement is such that for a resistance rm the relays Rn, Rn-1, ... Rm relapse. Thus in all cases the relapse of Rn brings up BR and during the release period of AR the mth marking wire is marked over front contacts of R1, .... Rm-1 and a back contact of Rm. The adjustable impedance X may be a thermistor, alone or in series with a large inductance, or a saturated diode or a pentode. Where an inductance is included the voltage change across the inductance may be used to operate the receiving device.
